‘The Voice’ Finale Pics: Best Moments

The Voice‘s fifth season finale was its most epic installment yet, and not only because we finally learned who would be crowned the winner. Both the Dec. 16 and the Dec. 17 shows featured amazing performances from A-List artists, giving the three Voice finalists a lot to live up to.

Celine partnered with Ne-Yo for a comeback performance of “Incredible,” the second single from her brand new English album Loved Me Back to Life. Lady Gaga also hit the stage, singing her fun and amazingly raunchy new single “Do What U Want,” while OneRepublic belted out “I Lived” from their new album Native.

Of course, this being The Voice, the true stars of the nights were the contestants — and, well, their coaches. Tessanne Chin, Jacquie Lee and Will Champlin all got a chance to shine, often among some of the most respected names in the music industry.

We’re surprised Tessanne was even able to make it through her duet of “Love Can Move Mountains.” Just one day earlier, Tessanne told HollywoodLife.com how nervous she was to meet her idol!
